Definitions

  • the present invention relates to a roller pump that delivers liquid such as blood, dialysis fluids, or medicines by pressingly closing an elastic tube using a roller rotating device. More particularly, the present invention relates to a roller pump suitable for medical applications.
  • a dialysis apparatus performing such a blood purification method or a blood artificial dialysis generally delivers liquid contained in an elastic tube by mounting a roller pump in a liquid circuit.
  • roller pump having a conventional structure of sliding and spreading a pump housing thereby improving efficiency of installing/removing of a tube in/from the roller pump.
  • an operation lever is reciprocated between an opened position and a closed position to drive a stator forwards/afterwards, arm parts are moved along guide holes to install/remove a tube.
  • roller pump disclosed in Patent Reference 1 has a problem that, while improving the efficiency of tube installing/removing, the increase of the number of parts makes it difficult to strictly ensure an interval precision between the pump housing and a roller, which fails to control a discharging flow rate of a fluid at high accuracy.
  • the present invention overcomes the above problem. It is an object of the present invention to provide a roller pump in/from which an elastic tube can be easily installed and removed, and which surely prevents the elastic tube from being accidentally released from the roller pump when the elastic tube should be set in the roller pump. It is another object of the present invention to provide a roller pump that can control a discharging flow rate at high accuracy, by ensuring an interval precision between (i) a slide part restricting an arrangement of the elastic tube and (ii) a roller.
  • a roller pump that delivers a fluid contained in an elastic tube by pressingly closing the elastic tube using a roller of a roller rotating device positioned on a base
  • the roller pump including: a slide part that is movable to a direction of the roller, and restricts an arrangement of the elastic tube; an operation part that operates (i) an opened state of the slide part where the elastic tube is installed in or removed from the roller pump, or (ii) a closed state of the slide part where the elastic tube is held in the roller pump; and an inhibit part that inhibits the slide part from moving to the opened state without the operation of the operation part, when the slide part is in the closed state.
  • the roller pump according to the present invention can ensure an appropriate interval precision between the slide part as a housing and the roller. As a result, the roller pump according to the present invention can control a discharging flow rate of the fluid at high accuracy.
  • the inhibit part may include a first link member and a second link member which are in contact with each other by respective substantially circular contact surfaces, the first link member has: one end rotatably connected to the slide part: and an other end rotatably connected to the second link member, and the second link member has: one end rotatably connected to the first link member: and an other end rotatably connected to a fixed part on the base, and a contact point between the first link member and the second link member exceeds a dead point of the second link member, when the slide part is changed from the opened state to the closed state.
  • the roller pump can prevent that the elastic tube is accidentally released from the roller pump while the roller pump operates.
  • roller pump according to the present invention a slide part in slide-ably contact with an elastic tube slides to and from the elastic tube, so that the elastic tube can be easily set in the roller pump. Furthermore, the roller pump according to the present invention can ensure an appropriate interval precision between (i) the slide part restricting an arrangement of the elastic tube and (ii) a roller. Thereby, the roller pump according to the present invention can control a discharging flow rate at high accuracy, and can surely prevent the elastic tube from being accidentally released from the roller pump while the elastic tube should be set in the roller pump.
  • FIG. 1 is a perspective view of a dialysis apparatus using a roller pump according to a preferred embodiment of the present invention.
  • a dialysis apparatus that performs blood artificial dialysis includes: a liquid circuit body 100; and a dialysis apparatus body 200 having a driving unit that circulates liquid into the liquid circuit.
  • this dialysis apparatus uses, for example, a roller pump 40 that will be described later with reference to FIG. 4 .
  • FIG. 2 is a perspective view of a roller pump 1 according to an embodiment of the present invention.
  • the roller pump 1 according to the present embodiment is characterized in including a pump slide 4 that has a wall surface in slide-ably contact with an elastic tube and slides to and from the elastic tube, which makes it easy to install and remove the elastic tube in/from the roller pump 1. Furthermore, the roller pump 1 according to the present embodiment is characterized in having slider links 6 and 7 that inhibit undesired opening (an opened state) of the pump slide 4 when the elastic tube should be hold in the roller pump 1.
  • the roller pump 1 includes a roller head 2, rollers 3, a pump slide 4, a pump block cover 5, a first slider link 6, a second slider link 7, a pump block base 9, a base 10, a motor 11, a cover lock 12, and tube guides 13.
  • the roller head 2 is a roller rotating device that is connected to the motor 11 and delivers liquid contained in an elastic tube by rotating together with the rollers 3 by drive force of the motor 11.
  • the rollers 3 are members arranged in the roller head 2.
  • the rollers 3 deliver liquid contained in the elastic tube by pressing the elastic tube that is arranged along the pump slide 4.
  • the pump slide 4 is connected with the pump block cover 5 via two slider links 6 and 7.
  • the pump slide 4 restricts an arrangement of the elastic tube, when an inner peripheral surface of the pump slide 4 is in contact with the elastic tube.
  • the pump block cover 5 operates an opened state and a closed state of the pump slide 4.
  • the first slider link 6 has a substantially circular contact surface in contact with the second slider link 7.
  • One end of the first slider link 6 is rotatably connected to the pump slide 4 using a support pin.
  • the other end of the first slider link 6 is rotatably connected to the pump block cover 5 using a support pin.
  • the second slider link 7 is rotatably connected to a fixed part formed on the base, using a support pin 8.
  • the second slider link 7 has a substantially circular contact surface in contact with the first slider link 6.
  • the pump block base 9 is integrally formed on the base of the roller pump 1.
  • the pump block base 9 has the tube guides 13 that hold the elastic tube.
  • the base 10 is included in the roller pump 1.
  • the motor 11 is a driving unit that is connected to the roller head 2 and drives the roller head 2 to rotate.
  • the cover lock 12 fastens the pump block cover 5 by being in connection to the pump block cover 5, when the elastic tube is set in the roller pump 1.
  • the tube guide 13 holds the elastic tube at predetermined positions on the base.
  • the pump slide 4 has a circular shape along a shape of circumference of the roller head 2.
  • the pump slide 4 is connected to the pump block cover 5 via the first slider link 6 and the second slider link 7, the pump slide 4 slides to and from the roller head 2 by opening and closing the pump block cover 5.
  • an operator can install or remove the elastic tube by opening and closing the pump block cover 5.
  • the elastic tube is to be set between an inner wall of the pump slide 4 and the roller 3. Then, rotating drive of the roller head 2 causes the rollers 3 to elastically press the elastic tube with a certain pressure, thereby pressingly feeding liquid contained in the elastic tube.
  • FIG. 2 shows three rollers 3 formed integrally in the roller head 2 at each 120-degree interval, but the rollers 3 may be two rollers arranged at a 180-degree interval, four rollers arranged at each 90-degree interval, or others.
  • the pump block cover 5 may have a shaft part that adjusts an interval between the roller head 2 and the pump slide 4, when the pump slide 4 is in a closed state where at least a part of the pump slide 4 contact the elastic tube, although this is not shown in FIG. 1 .
  • positional adjustment of the shaft part enables the roller pump according to the present invention to be used for various elastic tubes having different radius.
  • a position of the pump slide 4 or a distance of sliding of the pump slide 4 can be changed depending of radius of the elastic tube.
  • the pump slide 4 of the roller pump 1 according to the present invention is an independent member, and connected to the base 10 using a spring member so that the pump slide 4 can be adjusted forwards and backwards depending on a size of the elastic tube.
  • an angle of a contact surface between the pump slide 4 and the elastic tube is 120 degrees. Since use of two rollers causes roller slip regions which fails to press the tube, an angle of a contact surface of the rollers is generally 180 degrees. However, if a tube is installed or removed by moving the pump slide 4 in the manner as described above, a clearance between (i) an end of a part where the pump slide 4 is in contact with the tube and (ii) the tube is decreased. Thereby, 180 degrees of the contact surface is difficult to be achieved. Here, if the angle of the contact surface is decreased, it is necessary to increase the number of rollers to prevent that the roller is rotating but loses a contact with the elastic tube (namely, slipping). From the above reasons, a contact angle ( ⁇ ) between the tube and the wall surface of the pump slide 4 is preferably from 100 degrees to 160 degrees. Therefore, it is desirable to form three or more rollers at equally-spaced intervals (angles).
  • FIG. 3 shows a top view and a side view of the roller pump 1 of FIG. 2 , when the pump block cover 5 is fully opened (in a full opened state) and when the pump block cover 5 is fully closed (in a full closed state).
  • an elastic tube can be installed in or removed from the roller pump 1.
  • an operator can install or remove the elastic tube by a simple operation of opening and closing the pump block cover 5.
  • an angle between the pump block cover 5 and the pump block base 9 is 70 degrees, and an angle between the first slider link 6 and the second slider link 7 is 90 degrees, for example.
  • an angle between the first slider link 6 and the second slider link 7 is, for example, in a rage from -1 degree to - 30 degrees, exceeding 0 degree.
  • the range is from -5 degrees to -20 degrees.
  • FIG. 4 shows a top view and a side view of the roller pump 40 having a pump block cover 41, in each of a full opened state and a full closed state.
  • the pump block cover 41 in the roller pump 40 is different from the pump block cover 5 of the roller pump 1 of FIG. 2 .
  • the roller pump 40 shown in FIG. 4 has the pump block cover 41 that is smaller than the pump block cover 5 of FIG. 2 .
  • an elastic tube can be installed in or removed from the roller pump 40.
  • an operator can install or remove the elastic tube by a simple operation of opening and closing the pump block cover 41.
  • an angle between the first slider link 43 and the second slider link 42 is, for example, in a rage from -1 degree to - 30 degrees, exceeding 0 degree.
  • the range is from -5 degrees to -20 degrees.
  • FIG. 5 is an enlarged side view of a part of the slider links 42 and 43 of the roller pump 40 of FIG. 4(b) .
  • the pump slide 44 has a movement inhibit part 44a that inhibits a downward movement of the first slider link 43 and the second slider link 42.
  • the first slider link 43 has a movement inhibit part 43a at a position corresponding to the movement inhibit part 44, in order to inhibit a downward movement of the first slider link 43 and the second slider link 42.
  • a fixing part 45a is formed at the edge of a base 45 of the roller pump 40.
  • One end of the second slider link 42 is rotatably connected to the fixing part 45a using a support pin. Closing of the fixing part 45a restricts a backward movement of the second slider link 42 when the pump block cover 41 is in the closed state.
  • the pump slide 4 slides to and from the elastic tube by operating the pump block cover 5.
  • the roller pump 1 according to the present embodiment can install and remove the elastic tube in/from the roller pump 1 more easily.
  • the pump slide 4 when the pump block cover 5 is in the closes state, the pump slide 4 can not move backwards. Thereby, this prevents the pump slide 4 from accidentally moving backwards, thereby surely preventing the elastic tube from releasing from the roller pump when the elastic tube is set in the roller pump. In addition, this can keep a proper interval precision between the inner peripheral surface of the pump slide 4 and the roller 3. As a result, it is possible to keep high accuracy of a discharging flow rate of a fluid in the elastic tube, and achieve more stable delivering by an dialysis apparatus or the like using the roller pump 1 of the present invention.
  • roller pump of the present invention Although only some exemplary embodiments of the roller pump of the present invention have been described in detail above, those skilled in the art will be readily appreciate that many modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of the present invention. Accordingly, all such modifications are intended to be included within the scope of this invention.
  • the roller pump according to the present invention can be used as a roller pump used in an apparatus for circulating and supplying liquid such as blood or dialysis fluids by an elastic tube in the field of medical treatments.
  • the roller pump according to the present invention can be used as a roller pump that performs liquid delivering in artificial dialysis apparatuses and the like.
